WILLIAM H. DUBKEE, OF NEW YORK, N. Y.

DECK-PLATE.

Application filed February 6, 1907.

Specification of Letters Patent.

Patented March 24, 1908.

Serial No. 355,994.

To all whom it may concern:

Be it known that I, WILLIAM H. DURKEE, a citizen of the United States of America, and a resident of New York, in the county and State of New York, have invented certain new and useful Deck-Plates and the Like, of which the following is a specification, the same being a full, clear, and exact description ofthe invention, such as will. enable others skilled in the art to which it appertains to make and use the same.

This invention relates to deck plates and like articles by which access may readily be had to devices or apparatuses of different kinds located below the same, and the cover of which may preferably be held down in a watertight relation in the frame plate thereof, and it has for its object the provision of a device of the kind set forth of simple construction, and forming in operation a durable and efficient organization.

To attain the desired end, the invention consists in novel devices and combinations of devices as hereinafter explained.

In order to enable the invention to be fully understood, I will proceed to explain the same by reference to the drawings which ac company and form a part of this specification, and in which Figure 1 is a plan View of a deck plate constructed according to my invention; Fig. 2 is a view in section on the line 1, 2, Fig. 1, the members of the device being separated; Fig. 3 is a view in section taken on the line 3, 4, Fig. 1; Fig. 4 is a plan view of another deck plate in which my invention' is embodied; Fig. 5 is a view in section on the lines 3, 4, Fig. 4; and Fig. 6 is a view in section taken on the line 1, 2, Fig. 4, the parts of the deck plate being shown apart from each 2 other.

Like letters of reference indicate like parts in all the views.

Referring particularly by reference symbols or characters to the drawings, A denotes the face plate or frame formed with eyes I) for screws and having a shouldered recess a, and an annular flange or ring a depending therefrom provided with a groove 9.

B indicates a plate or cover having a depending flange and a preferably integral finger recess D and a projecting rim or edge S to engage the annular shoulder a, and also being provided with one or more lugs F formed with an interior recess having a contracted mouth. A spring bolt or dog 0 works in the said recess and has preferably an upset end (1 to prevent abnormal forward movement of the same when actuated by the spring e, and also has an enlarged portion C and a rounded head 20 which projects through the mouth. C.

Upon the cover plate B being applied to the frame or face plate A, the said cover may be snapped in by the head 1) of the bolt 0 engaging the groove 9, and intermediate the rim or edge S and the shoulder a, I preferably place a thin strip of packing or rubber g in order to form a watertight jointure.

The cover plate B may be applied to the frame or face plate A in different positions as regards the location of the finger recess D, and the said cover plate is also readily detachable again from the ordinarily stationary frame or face plate A, as is clearly shown in the drawings, the said engagement and disengagement of the parts being accomplished by a simple pressure, or pulling action, on the cover.

In Figs. 4 to 6 inclusive, in which are shown another embodiment of my invention, the face plate A is engaged by the cover B, and the lugs F with spring dogs or bolts are located in the rim of the frame or face plate, and the groove g is positioned on the outer edge of the depending flange or ring of the cover, and it will be clearly seen that this style of cover and frame plate may also be readily engaged and disengaged at will.

The cover B or B may be permanently secured to any suitable retaining object, as the plate f, as by means of intermediate flexible means, as a chain f, in order to prevent. the said cover from becoming mislaid when detached from the face plate A or A.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obviously modifications will occur to a person skilled in the art.

What I claim as my invention is 1. A face plate or frame having a shouldered recess and an annularflange depending from the shoulder, and a plate or cover having a finger recess, and a projecting rim to engage the said shoulder, and a depending flange to register with the first named flange, in combination with means, consisting of a self locking device comprising, a groove and a spring dog to coact therewith, for interlocking and detaching the two parts by a simple pressure, or pulling action, on the COVGI'.

2. A face plate or frame having a shouldered recess and an annular flange depending from the shoulder, and a plate or cover having a finger recess, and a projecting rim to engage the said shoulder, and a depending flange to register with the first named flange, in combination with means, consisting of a self lockingdevice comprising a groove-and a spring dog to .coact therewith, for interlocking and detaching the two parts by a simple pressure, or pulling action, on the cover, and also. with means whereby a watertight jointure between the two plates is formed.

3. A face plate or frame. having a shoulhaving a finger recess, and a projecting rim to engage the said shoulder, and a depending flange to register with the first named flange, in combination with means, consisting of a self locking device comprising a groove and a spring dog to coact therewith, for interlocking and detaching the two parts by a simple pressure, or pulling action, on the cover, a suitable retaining object, and intermediate flexible connecting means for attaching the cover thereto.

In testimony of the foregoing, Ido hereby sign the same in the city of New York, county and State of New York this 21st day of December 1906.

WILLIAM H. DURKEE.
